LOW LEAKAGE CHARGE RECYCLING TECHNIQUE FOR POWER MINIMIZATION IN CNTFET CIRCUITS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Carbon Nanotube Field Effect Transistor (CNTFET) is one of the most promising candidates in the near future for digital design due to its better electrostatics and higher mobility characteristics. Parameters that determine ...
OPTIMIZATION OF BIODIESEL PRODUCTION FROM WASTE FRYING OIL OVER ALUMINA SUPPORTED CHICKEN EGGSHELL CATALYST USING EXPERIMENTAL DESIGN TOOL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
An optimization of the biodiesel production from a waste frying oil via a heterogeneous transesterification was studied. This present study is also aimed at investigating the catalytic ehaviour of the alumina supported ...
PARTICLE MOTION OVER THE EDGE OF AN INCLINED PLANE THAT PERFORMS AXIAL MOVEMENT IN A VERTICAL LIMITING CYLINDER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Differential equations of a relative material particle motion over the edge of an inclined flat ellipse that rotates around the axis of a vertical limiting cylinder have been deduced. The position of a plane relative to ...
WELDING OF NITINOL BY SELECTED TECHNOLOGIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Nitinol is a perspective alloy that is difficult to weld because of its high sensitivity to heat, atmospheric gases and the NiTi phase instability. We evaluated several welding techniques with regard to their applicability ...
MODELLING SIMULATION AND PARAMETER IDENTIFICATION OF ACTIVE POLLUTION REDUCTION WITH PHOTOCATALYTIC ASPHALT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
We develop and implement a numerical model to simulate the effect of photocatalytic asphalt on reducing the concentration of nitrogen monoxide (NO) due to the presence of heavy traffic in an urban environment. The contributions ...
AN ANALYSIS OF SPATIAL STRUCTURE OF URBAN REGIONAL NETWORKS USING GIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Road network is the foundation of the urbanization process. Initially, it represented an indispensable part not only for the very existence of cities but also for their further economic and social development. Gradually ...
NON-DESTRUCTIVE INSPECTION BY INFRARED THERMOGRAPHY OF RESISTANCE SPOT WELDS USED IN AUTOMOTIVE INDUSTRY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Resistance spot welding (RSW) is one of the main joining technologies of thin sheets in the automotive industry. Key factors affecting the strength of the RSW joint are the nugget diameter, asymmetry, expulsions, intended ...
SIMULATION OF LOW-GRADE COAL COMBUSTION IN REAL CHAMBERS OF ENERGY OBJECTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The aim of the work is to create new computer technologies for 3D modelling of heat and mass transfer processes in high-temperature physicochemically reacting environments that will allow to determine the aerodynamics of ...
TECHNOLOGY OF PRODUCING REINFORCED CONCRETE COLUMNS OF CIRCULAR CROSS-SECTIONAL AND INVESTIGATION OF THEIR STRAIN-STRESS STATE AT TRANSVERSE-LONGITUDINAL BENDING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The paper presents a method of producing Circular Cross-Section Columns (CCSC), which can provide sufficiently precise dimensions, with longitudinal reinforcement securely fixed in special plugs. An investigation procedure ...
INDICATORS FOR COMMON CROSSING STRUCTURAL HEALTH MONITORING WITH TRACK-SIDE INERTIAL MEASUREMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
This paper focuses on the experimental study of an alteration in the railway crossing dynamic response due to the rolling surface degradation during a crossing’s lifecycle. The maximal acceleration measured with the ...
